Oddly without any repairs, replacements etc, we have had a stable Mux 2 for 10 days. What's the betting it goes tonight.

Whats going on? For the passed week now,we have got our pictures back. The signal all of a sudden seems to be really good with not even a hint of freezing. We have had a terrible time of it from Beckley, so this is very welcome. My neighbours are saying exactly the same thing. Have you done something up there at Beckley, and is it going to last?

We had perfect freeview reception prior to the "fire", now we have intermittent reception on ITV1, channel4, channel5, it's a ludicrous situation and we are expected to replace our aerial. Our opinion is that the Oxford transmitter services have got it wrong, and should pay for the necessary changes. Can we have a reply from "them" please?

You are responsible for your reception, the transmission company is only responsible for the transmission.

Tony Mallett: some viewers in the area have found that the new transmission aerial produces higher signal strength than the old, and that causes problems with amplifiers. If you have an amplifier or booster, I suggest removing it to see if that improves matters. If not, try adding an attenuator to reduce the signal strength.

If you could provide your postcode, we can look at the prediction and the distance to the mast to see if your problems are more likely to be too much or too little signal strength, or other types of interference.

I have just heard that, pror to the fire, MUX2 ( which carried ITV1, C4, Five, etc. ) was transmiited from its own aerial above the main antenna. Transmission of that MUX has now moved down to the main antenna.
So we're not all going mad, the receved signal strength of those channels really has dropped.

Paul: Before the main transmitting aerial was replaced, there were panels on top of it. These were used, the best I can tell, to increase the power-handling capability of the main aerial. The first four analogue channels and the six multiplexes were all combined onto the cylinder.

Multiplexes 1 and B also have supplementary panels below the main aerial, on one corner of the mast. Channel 5 analogue has its own skew-fire panels further down.

Source: U.K. Television Stations (UHF Digital System) and Former U.K. Television Stations (UHF Analogue System) showing muxes 2, A, C and D at an average height of 289m above sea level (AOD) and muxes 1 and B at an average 277m, and BBC1/2/ITV/C4 at 289m. Photographs at mb21 - The Transmission Gallery - 277m is actually in the middle of the FM radio panels immediately below the main antenna.

The mux 1 and B panels were moved down closer to the C5 array in order to fit the new reserve aerial, which took over services in late 2009 to allow the old cylinder to be replaced: http://tx.mb21.co.uk/gallery/oxford/oxford06.php

The
new aerial was fitted in February 2010: mb21 - The Transmission Gallery . When the broadcasters tried to put it into service it caught fire, and had to be replaced.

The new, new aerial was fitted in August 2010 and went into service towards the end of the year. As far as we know, all services (except C5 analogue) are combined onto this one transmission aerial, just as before. At switchover all six high-power digital multiplexes will be combined onto this one aerial. (RG47SH)

I live in Buckingham. I bought a new Panasonic TV and a new Sony DVD/Recorder in July 2010. I had a new aerial installed. They seemed to work perfectly until the end of Dec when the DVD stopped picking up the signal from all channels except BBC1 and BBC2. The TV works perfectly when the DVD is switched off but as soon as the DVD is switched on the signal goes from the TV. The DVD has been tested in Milton Keynes and has shown it works perfectly. Do I have to wait till Sept 28 before I can use my new DVD?! What's it all about?
